Product Description

PF-2 Fluoride and Arsenic Reduction Filters (Set of 4)

The PF-2 reduction elements screw onto the bottom of the Black Berkey water purification elements and work in conjunction to adsorb the following unwanted elements found in drinking water.

• Fluoride
• Arsenic V and pre-oxidized Arsenic III
• Other residual heavy metal ions


FLUORIDE: Testing for fluoride was based on 20-30ppm of the ion in the influent aqueous solution at a flow rate of no more than 3 gpm (11 lpm) per cubic foot of media. Results of < 1ppm of the fluoride ion in the effluent were typical for the media (>95% reduction). Under optimum conditions, effluent concentrations of less than 50 ppb were readily achieved (>99.75% reduction).

ARSENIC: This product uniquely targets the entire family of arsenic oxide anions as well as the arsenic cations.

REPLACEMENT:  Under normal circumstances, a set of 2 fluoride filters should be replaced every 1000 gallons

  1. Fluoride and Arsenic Filters (Challenges and Benefits) 3 Star Review

    Posted by on 17th Feb 2018

    I have used my Berkey water purification system for a little over one year. I purchased the maximum number of filters for my Big Berkey (4 black elements and 4 PF-2 filters.)

    The quality of the water is excellent. The time frame for capturing the filtered water is extremely slow. Without the PF-2 filters it is substantially faster and the bottom chamber can hold substantially more water (since there is NO displacement from the 4 PF-2 filters.) I have chosen quality over speed. For those looking to buy this equipment, I suggest you also purchase glass 1/2 gallon bottle to store your daily filtered water. This way you don't have to concern yourself with the speed of filtration.

    S.N. I have (multiple times) properly cleaned and re-primed the black elements and re-checked the flow from the PF-2 filters. This is simply the way my system works.

  2. The water tastes better, I love my Berkey! 4 Star Review

    Posted by on 7th Dec 2016

    I could tell it was time to put in my new fluoride filters when my water taste changed. So much better now. I did find I has an oil film with this batch but after some research it just needed to filter more. This was a pain for a bit.

    Posted by on 5th Mar 2013

    The water tastes great! We use it for almost everything. We fill bottles with our Berkey water so when we leave our house the kids have the best and won't consume the harsh chemicals and fluoride that's in most city water.

  8. Safe water at last! 5 Star Review

    Posted by on 15th Jan 2013

    I purchased a Royal Berkey last year. My city adds sodium fluoride to the water. I have 4 first stage filters and 4 fluoride filters installed in my Berkey. The water that comes out of the spigot is THE BEST WATER I have drank. I had been using bottled water to avoid the fluoride and other chemicals. The Royal Berkey paid for itself in less that eight months!

  9. Get rid of flouride 4 Star Review

    Posted by on 28th Feb 2012

    These filters do a great job of filtering out fluoride from your water! Remember to screw them on with eight turns.
